(WBIR-Knoxville) Knoxville police are investigating an "unknown" death at the University of Tennessee Medical Center.

Dr. Zackary Rose, 28, was found dead Monday morning. On Sunday, he came to work at 7 a.m. to start a 24-hour shift and was last seen at about 3 p.m.

Rose was paged several times at about 1:45 a.m. Monday. When he didn't answer the page, another student doctor went to look for him and found his body in a second floor call room bed.
